### 4.2.2.8 TCP Connection State Diagram: RFC-793 Section 3.2, page 23

There are several problems with this diagram:

1. The arrow from SYN-SENT to SYN-RCVD should be labeled with "snd SYN,ACK", to agree with the text on page 68 and with Figure 8.

2. There could be an arrow from SYN-RCVD state to LISTEN state, conditioned on receiving a RST after a passive open (see text page 70).

3. It is possible to go directly from FIN-WAIT-1 to the TIME-WAIT state (see page 75 of the spec).
